Work in progress game demo for the Pimoroni Picosystem. Don't expect this to do much right now.
These are built and managed by Alire.
I use GIMP to create 8-bit 8x8 grayscale bitmaps, which are transformed by res/make_resources.py into 2-bit ELF objects and statically linked into libresources.a. Those symbols are imported by src/bitmaps.ads.
You need a arm-eabi-objcopy and arm-eabi-ar in your PATH and the Python Pillow Library (python3-pil) installed to run make_resources.
cd res
python3 make_resources.py
cd ..
Depends on Alire
alr build
If you don't have a SWD debugger connected to your Picosystem, you can generate a .uf2 binary that can be loaded over USB by holding the X button while plugging it in. elf2uf2 comes from pico-sdk and needs to be in your PATH.
